I didn't forget about typing... I've just struggled to have everything prepared for all 6 classes everyday. Anyway... I'm going to try to do better at this part specifically.

Before we begin, let's take a look back through history.
Here's a video from over 50 years ago.

System Changeover
System Changeover
Illustration by Glenn Harvey
The next part of systems is system changeover; that is the process used to switch from one system to another. An individual changing their own personal system, or that of their family, often won't have a lot of thought or concern around it. However, the larger the environment, the more problematic and complicated a system changeover may be. A company or organization likely handles and stores people's personal data, financial information, and may also be tied to people's livelihood, health and wellness, or a region's infrastructure.
A system changeover for a medical facility, power plant, or communication provider can result in significant consequence should something go awry, or should service be discontinued temporarily. For these reasons, there are a variety of strategies to facilitate system changeover.
The vast majority of the time, it's not personal, but rather it comes down to money. Usually, it's just about figuring out the best ways to increase profits and/or reduce expenses.
Isn't that comforting?
Isn't that concerning?
Companies and organizations have a variety of expenses, some of them are harder to control, like rent, utilities, and taxes. Others are easier to control, like how many employees you have. Often times, the work that needs to get done doesn't change, you just have less people to do the same work. So the scope of the individual's job increases. This increasing demand is sometimes called Job Creep or Job Scope Creep.
Marge Schott was the second woman to own a North American major-league team, the Cincinnati Reds franchise from 1984 to 1999, without inheriting it. She was banned from managing the team a few times in the 90s due to controversial and racist statements, which have also tarnished her legacy and memory.
Sometimes, a system changeover is the whole system or process a company or organization relies on. Often times a new system may replace just part of an organization's or company's operations, and is implemented into an already establish pre-existing larger system or series of systems; like moving to Canvas while still using Clever, Skyward, etc. Switching systems will usually result in increased short terms costs, which will likely include manhours, training, as well as potential financial expenses. There may also be resistance from employees or customers when a new system is implemented. Planning should be done prior to implementation to attempt to reduce negative effects of the changeover.
Differing implementation methods have differing trade-offs and risks, the 'best method' is always situationally dependent. The implementation methods are as follows:
Parallel: in this implementation method, both systems work in parallel for a short period of time. This method also allows measuring output of the new system before the older system is taken offline. If the new system's functionality is not satisfactory, the company can still rely on the old system while trying to iron out any issues with the new system. This method can be expensive and taxing, as you are running both systems at the same time. This may require additional computer or network resources, additional man hours, and financial expenses to keep both running at the same time. If the two systems are drastically different, this can be extremely ineffecient for however long the changeover takes.
Big Bang/Direct/Immediate: in this implementation method, as soon as preperations are made, one system is entirely discontinued, and the other brought online. This method is the least taxing on computer and network resources, but requires frontloading training prior to the changeover. Additionally, any data that needs to be transfered from one system to the other may need a tertiary system or external location while the changeover occurs.
Pilot: this implementation method has a smaller portion of an organization or company change to the new system, called the pilot group or pilot site. This is fairly common in larger organizations and companies that have multiple divisions or sites. This implementation method can allow time to test the new system and iron-out issues with lower risk before it is implemented to the whole organization. Once the new system is succesful for the pilot group, changeover method for the rest of the organization can be planned. The pilot group can serve as a model when the the new system is adopted.
Phased: this implementation method sees the company or organization convert one module or part of the system at a time over a period of time. This may mean the new system and old system may need to be similar enough for data or processes to go back and forth between the two. Training time is extended and the process overall will generally take longer as each phase of the new system is implemented seperately. These phases of implementation may be based on certain processes or functions across the whole organization, or may be based around departments or teams within the organization.
As the system changes, so too must we. This includes learning new technologies and gaining new skills. Over time, we continue to automate more and more tasks, and the skills and abilities and knowledge someone needs to get and keep a decent job continually increases.
The purchase of a 2,832.49 computer in
1995 dollars would be around 6k today.
We can look at the past and see obvious examples of how the advancement of tech changed jobs and whole workplaces. We can see technology developments right now that will likely cause changes in our own future; although it's somewhat guesswork to try to figure out exactly how.

Coming Up Next
We'll continue our notes as we continue the topic tomorrow.
Tomorrow, we'll also look a bit into Data Migration and how this topic relates to Data Migration.
For today/tomorrow's class periods, if you have time, start doing a bit of research as well.
Find 3 examples of systems that includes technology/human interaction.
